Answer:
Expression is '98 divided by 0.005' i.e.
.
Step-by-step explanation:
We have that,
The quotient of 8 divided by 0.001 is given by,
=
= 8000.
It is required to find a division expression having quotient greater than 8000.
Let us consider,
'98 divided by 0.005'
i.e. 
i.e. 
i.e. 98 × 200
i.e. 19,600
Thus, the get the quotient of the new expression 19,600 > 8000.
Hence, the required expression is '98 divided by 0.005' i.e.
.
The population Pa of insect A after t years is given by the equation
Pa = 1.3(1-0.038)^t
while the population Pb of insect B after t years is
Pb = 2.1(1-0.046)^t
We equate the above expressions to find the number of years t it will take the two populations to be equal:
Pa = Pb
1.3(1-0.038)^t = 2.1(1-0.046)^t
1.3(0.962)^t = 2.1(0.954)^t
These are the equations that can be used to determine how long it will be before the populations of the two species are equal.
We can now solve for t:
(0.962)^t / (0.954)^t = 2.1/1.3
(0.962/0.954)^t = 2.1/1.3
After taking the log of both sides of our equation, number of years t is
t = log (2.1/1.3) / log (0.962/0.954)
t = 57 years
Therefore, it will take 57 years for the population of insect A to equal the population of insect B.
